Active clinical trials for "Breast Neoplasms"

A prospective phase II study conducted at the Cancer Hospital Chinese Academy of Medical Sciences to compare the effectiveness of eribulin combined with lobaplatin in the treatment of recurrent or metastatic triple-negative breast cancer

The standard method for localizing non-palpable breast cancer is currently preoperative wire-guided localization, its positive margin rate still remains around 20-50%. This study aims to compare the accuracy and efficacy of wire vs. combined breast tissue markers in localizing non-palpable breast cancer.

The aim of the study is to find out whether supervised physical exercise during cancer drug treatment improves the effectiveness of the treatment in metastasized breast, kidney, ovarian and prostate cancer compared to unsupervised exercise. In addition, the investigators are investigating whether the use of atorvastatin combined with guided group exercise training would further improve the response to cancer treatment.

ExteNET study explored neratinib prolong anti-HER2 therapy after trastuzumab therapy found that it can improve disease-free survival in patients with lymph nodes positive; In addition, the subgroup of patients with residual tumors after neoadjuvant therapy was found to improve the survival. However, no conclusive conclusions were reached. However, since the study was carried out early so only trastuzumab treatment was used, it is urgent to carry out research that is more in line with current clinical practice and bring more benefits to patients. To explore whether pyrotinib can further reduce the risk of recurrence from previously diagnosed HER2-positive breast cancer after treatment with trastuzumab and pertuzumab or T-DM1.

Background: Mastectomies are traditionally performed under general anesthesia (GA), often with the addition of regional anesthesia for post-operative pain relief. Thoracic paravertebral blocks (TPVB) had previously been described in the literature to be sufficient for intra-operative anesthesia as an alternative to GA. A 2021 literature review by Cochrane Library comparing paravertebral anesthesia (with or without sedation) to general anesthesia for patients undergoing oncologic breast surgery showed that TPVB could reduce post-operative nausea and vomiting (PONV), hospital stay, postoperative pain and time to ambulation. It also resulted in greater patient satisfaction compared to GA. The aim of this study is to demonstrate the efficacy of single-injection TPVB done under ultrasound guidance for patients undergoing breast cancer surgery without axillary node dissection. Hypothesis: Single-injection thoracic paravertebral block is non-inferior to multiple (3) injections for oncologic unilateral breast surgery anesthesia. Methods: The current study is a prospective randomized controlled trial of patients undergoing oncologic breast surgery without axillary node dissection or immediate reconstruction. Patients will be randomized into two groups; thoracic paravertebral block (TPVB) single-injection or TPVB multiple (three) injections. Significance/Importance: Oncologic breast surgery performed under TPVB and sedation lowers the risks of post-operative nausea and vomiting, decreases peri-operative use of narcotics, decreases pain scores at rest and on mobilization and leads to better overall patient satisfaction when compared to GA. It also leads to shorter hospital stays. Most studies use multiple injections to perform the block. Even though the risks associated with TPVB are low (3.6 per 1000 surgeries), the single-injection technique could reduce the risks even more. One injection is also easier to perform and of shorter duration, leading to greater patient tolerance and less side effects related to blocks performance duration such as vaso-vagal reactions or general discomfort. To date, no studies have compared the efficacy of single-injection paravertebral block and multiple injection techniques as the main modality of anesthesia for breast cancer surgery.

This study evaluates the safety and effectiveness of the da Vinci SP Surgical System compared to Open NSM in Nipple Sparing Mastectomy procedures.

The purpose of this study is to assess the feasibility, acceptability, and preliminary effects of a digital (web and mobile-phone-based) program to improve lifestyle behaviors (physical activity, dietary intake) among Hispanic female cancer survivors and adult daughters.

The multicenter, two-cohort, non-comparative, open-label, phase II clinical trial SABINA aims to analyze the safety and efficacy of MEN1611 in monotherapy and in combination with eribulin, a non-taxane chemotherapy agent, in Hormone Receptor (HR)-known/Human Epidermial Growth Factor Receptor 2 (HER2)-negative, phosphatidylinositol-4,5-bisphosphate 3-kinase catalytic subunit alpha (PIK3CA)/ Phosphatase and Tensin Homolog (PTEN)-altered, unresectable locally advanced or metastatic metaplastic breast carcinoma (MpBC) patients. A run-in phase for safety and tolerability of MEN1611 in combination with standard doses of eribulin will be conducted as an initial step of the cohort A. This first step aims at evaluating the dosing schedule of MEN1611, by analyzing the toxicity profile of the combined regimen. With the background of the first-in-human study (PA-001EU), the safe dose of MEN1611 has been established as 48 mg orally BID (two intakes of 3 capsules of 16 mg each, for a total daily dose of 96 mg MEN1611 free-base).

TQB3909 is an inhibitor targeting B-cell lymphoma (BCL)-2 protein. By binding to BCL-2 protein, TQB3909 releases Pro apoptotic proteins such as BCL-2-Anatagonist/Killer 1(BAK), BCL-2 associated X (BAX) protein and BCL-2 associated death (BAD) protein, promotes the release of cytochrome c from mitochondria, phosphatidylserine eversion, stimulates caspase 3/7 activity and caspase 3/9 cleavage, and induces apoptosis.

This is a Phase 1, first-in-human, open-label study designed to evaluate the maximum tolerated dose (MTD), recommended phase 2 dose (RP2D), safety, tolerability, pharmacokinetics, pharmacodynamics, and preliminary anti-tumor activity of RLY-5836 in advanced solid tumors in participants harboring a PIK3CA mutation in blood and/or tumor per local assessment. The study consists of 2 parts, a dose escalation (Part 1) and a dose expansion (Part 2).
